Question

tìm X :

720 : ( X x 2+ X x 3)= 2x3

Answer 1

720 : ( X x5 )= 6

X x 5 = 720 : 6

X x 5 =120

X      = 120 : 5

X = 24

chúc bạn học tốt

Answer 2

720:(x.2+x.3)=2.3

=> 720:[x.(2+3)]=6

=> x.5              =720:6

=> x.5              =120

=> x                 =120:5

=> x                 =24

Vậy x=24

Answer 3

720 : ( X x 2+ X x 3)= 2x3

720 : ( X x 2+ X x 3)= 6

720 : [X x (2+3)] = 6

720 : (X x 5) = 6

720 : 5 x X = 6

X = 720 : 5 : 6 

X = 24

Answer 4

720 : ( X x 2+ X x 3)= 2x3

720 : ( X x 2+ X x 3)= 6

720 : [X x (2+3)] = 6

720 : (X x 5) = 6

720 : 5 x X = 6

X = 720 : 5 : 6 

X = 24

Answer 6

720 : ( X x 2+ X x 3)= 2x3

720 : ( X x 2+ X x 3)= 6

720 : [X x (2+3)] = 6

720 : (X x 5) = 6

720 : 5 x X = 6

X = 720 : 5 : 6 

X = 24

Answer 7

720 : ( X x 2+ X x 3)= 2x3

720 : ( X x 2+ X x 3)= 6

720 : [X x (2+3)] = 6

720 : (X x 5) = 6

720 : 5 x X = 6

X = 720 : 5 : 6 

X = 24

Answer 8

720 : ( X x 2+ X x 3)= 2x3

720 : ( X x 2+ X x 3)= 6

720 : [X x (2+3)] = 6

720 : (X x 5) = 6

720 : 5 x X = 6

X = 720 : 5 : 6 

X = 24

Answer 9

720:[Xx2+Xx3]=2x3

720:Xx5=6

Xx5=720:6=120

X=120:5=24
